Hi,

I run Windows and I started using 64 bit PostgreSQL 9.3 a month ago.
I have several PostGIS databases on localhost, with these statistics:

Looking in process explorer, I see unusual size for postgres server process, i.e. working set reported around 1GB: http://i.imgur.com/HmkvFLM.png (same in attachment)

I also use SqlExpress server with several databases (including spatial) but that doesn't go above 100MB in Private Bytes and around 1 MB in Working Set.

I wanted to ask, if this is normal, or there is some problem with my server setting?


Thanks
